Be it known that I, KARL SGHLEYmni, a. subject ol' the King of Bohemia, and residing at lfilioiiitz, Bohemia, Austrian Empire,

olf Combustion which escape into the siiioliebox without being thoroughly utilized are sucked into the 'fire-box again for reeembus-- tion in suoli manner that the development of (laine in the fire-box is not only not arrested, but, oii the contrary, is actively assisted and the generation of steam accelerated end increased, while Coal is eeeiioiiiized and smoke avoided.

The improvement. consists in the 'products of eonihustion wliieli are Conducted from ihe siiioke-hox int-o the fire-box through the well-known suction-pipe being mixed with a suitable quantity of air by special ineens and iii the intensity of the suelion oi' these products of combustion and of the air being controlled and regulated corresponding to the ehiiiineyedraf-t.

The improved smoke-Consumer is iilustrated in theeaeeoiiipanying dra-Wings, iii whieh it is shown applied, by werf el' exinnple, to a loeoiiiotive-boiler. y

rl`he sueionqiine l, which eonneets the smoke-box 2 with the :ish-pan 3, is seeured I :it one end' to an air-inlet easing 4, located below the sxiioke-liox, and aty the @the oud to a smoke and air ejector 5, located iii the ash-pan.

The ejector, Figs. l and 2, consists of avereiur'e .iolav-wz-:isun me; aipiiralius, is sei in tical east-iron easing' (i, having' flanges lieli'iv." and above and having also a lateral ilaiige to eoiiiieetthe pipe l. Nithin the easing 6 there is located an annular perforated pipe 2, to which a pipe i0, eontroiled by a valve 1l, eoiiduets dry steam from the boiler. The steam passes upward through the perforatiens i? and assists the suction action of the ejector. The oz..- iig 6 is widened below', and in this enlarged part .l2 a fiat eene 'i3 is provii'led, the heielitoi' ivliieh een be iidjiieed frein the i'eot-'iiate by means of e, systeiii oi rods ll.- arid handfwheel i5, whereby the en trainee oi' air into the eje-eter emi lie rege lated. l

At the top el. the easing G there is eonneeiued pipe i6, which projeets through the grate l? into the lire-box 39. This eine 'le is surrounded by a staal?. of rings 18, which pre seiitgiibs i9 on the inside, so that passages 2f() formed between the pipe 16 and t .e rings Through 'these 20 fresh air iows iiitortlie fire-inox 3). and the rings and the pi'oe i6 are Cooled, whereby they are bet-ter aele "Lo resist izlie aetiori ei' the i'lziines. lies next te the liaiiies is Worn out, the ringe can be tureed iii order that the other not vet vrom parte lying next, to tube-pleite iiia' be exposed te the direct action of the iiaines.

- partly filled 1with a and funnel 25 will cause aV strong draft in the direction of the fire-box, stronger than in the v ucts of combustion with an anfple supply of fresh air and to maintain the draft in the pi' e 1 in a deiinite relation to the dra-ft in t e chimney or in the upper part of the smokebox. It is thus necessary always to know exactly the diii'errnce between thedrai't in the funnel 25 or pipe l and that in the top part of the smoke-box (above the top row of boiler-pipes) or in the chin ney, since otherwise in the event of only slight suction there would be practically no return of the products of. combustion, while in the .cese of an unduly strong draift there would be a serious Waste of steam, and lowing to the strong inrush into the lrire-box the `iire would be choked. For this purpose ya differential draft-meter 41 is employed, one form of the apparatus being shown 'in Fig. 6. It is mounted on some part where it can be readily seen by the engineer and consists of a U- shaped glass tube 31, secured to a plate 32, providedwit-h a scale, The one linib 33 oi' the tube 31 is connected by the .tube 33.with the' 'smoke-chamber above the top row of boileripes or with the chin ney,'vvhile the other iIr-.b 34'is connected by the tube 34 with the pipe 1 or funnel 25. The U-tube is suitable liquid, so that the reading is zero in bot-h liinbs when the boiler is not heated. When the boiler is fired up and the smoke-consumer operates, the liquid in the U-tubc changes its position. lThe more intense the suer ion through the ejector 5 the higher the liquidfwill rise in the linzb 34, which c'omniunicarcs with the pipe-1. The difference, for exanzplc, when the locolnoi ive is standing andv the sra-riing-valvey wholly o en is eighty to one hundred uillin eters. v Yhen the locomotive is running,t hc diilirrnce decreases, (ming to the draft inthe chin ney, to thirty to fiity nillindeteis. it is thus nrcessary to dctcrn-:ine this difference experimentally and. niark i t on the seale'lor dill'crent locomotives and different ly-ioreed lires or 'for different kinds of coal. By incluis ci this differential draft-meter 4f, therefore7 the (irait can be accurately determined at any moment, -nd by actuaiiinr the valve ll and the air-inlet devices in the ejector and the casing both the quantity combustion sucked up and the anmunt olA fresh air dreun in can hrregulated.

pipe l, and ejecthe products ci The toughened cast-irn box 23, which is built into the lower iire-box arch 24, is for the j purpose of protecting the pipe 16 of the ejecl tor by means ot the screen 22 and of causing the products of combustion which are blown into the box 23 to be partly consumed by the glowing walls of the same and partly deliected downwardly toward the giate, where they rr ingle with the other furnace-gases.

In Figs. 7-9 another form of construc- I tion of the regulating device for the smoke I and an' ejector 5 and the air-inlet casing 4 is shown. Accordingto this modification the with perforated plate 35 and a. damper 37, furnished with corresponding pertorations and, rotating about the central bolt 36. In this Ymanner the holes in the plate 35 can be opened nore or less, as required. The rotary dairl per 37 in the ejector 5 is actuated by a rod 38 and auxiliary mechanism from the foot-plate ofthe engine.

The herein-described smoke-consuming apparatus can be en'ployed not only for the boilers of locomotives, but also for those of ships and likewise for stationary boilers.
